Details

In the Linux kernel, the following vulnerability has been resolved:

RDMA/rxe: Fix responder length checking for UD request packets

According to the IBA specification: If a UD request packet is detected with an invalid length, the request shall be an invalid request and it shall be silently dropped by the responder. The responder then waits for a new request packet.

commit 689c5421bfe0 ("RDMA/rxe: Fix incorrect responder length checking") defers responder length check for UD QPs in function copy_data. But it introduces a regression issue for UD QPs.

When the packet size is too large to fit in the receive buffer. copy_data will return error code -EINVAL. Then send_data_in will return RESPST_ERR_MALFORMED_WQE. UD QP will transfer into ERROR state.
